Master of Darkness is a platform game, very similar to Castlevania. The plot has the player entering the role of a Ouija board-playing psychologist named Dr. Ferdinand Social. He is looking to defeat Count Dracula, who is behind a series of killings in London that have been attributed to Jack the Ripper. However, Jack the Ripper is indeed responsible, for he is using the victim's bodies and fresh blood for sacrificial offerings – as part of a dark ritual being performed by Count Massen to resurrect Dracula. Also taking some part in the murders and the dark ritual is a mysterious Psychic Girl, who is possessed by an evil Skull Spirit.
